Age differences among psychiatric inpatients on the MCMI.
A 2 x 2 x 3 MANOVA was applied to MCMI BR scores obtained from 310 newly admitted psychiatric inpatients. The study's purpose was to test the effect of patients' age (age less than 36 vs. age greater than = 36), race (White/Black), and diagnosis (paranoid schizophrenic/nonparanoid schizophrenic/non-psychotic, nonaffectively disturbed) across MCMI personality and clinical syndrome scales. On the MCMI personality syndrome scales, age, race, and diagnosis were significant. Racial differences were consistent with recently reported research (Davis, Greenblatt, & Pochyly, 1990), but the significant differences in diagnosis were opposite the direction that might be predicted from the MCMI manual. Older patients tended to produce lower symptom scale scores than younger patients, with the most meaningful difference found on the Drug Abuse scale.
